Long time Lightroom user. Lightroom Classic 11.4.1 and Windows 10.
Recently I noticed that my C drive suddenly gained about 100 GB of free space. Looking at back ups I tracked it to my previews folders, and it happened about 2 weeks ago all at once..
I have 3 catalogs, 1 for my paid work, 1 for family photos, and 1 for personal projects. All 3 catalogs are set to delete 1 to 1 previews after 30 days. But in my experience, the preview folders never get smaller, they only continue to grow. 1 preview folder dropped from 24 GB to 15 GB, another from 104 GB to 47 GB, and another from 63 GB to 30 GB. As I said, it all happened at the same time about 2 weeks ago. Lightroom is installed on my C drive and all photos are on external drives. Everything seems to be working as normal. But I find it strange this would happen. This might have happened about the time I did the last update, not sure. Anyone have any thoughts on why this would happen?

The latest update includes a new feature, that deletes ‘orphaned’ and out of date previews, because these are redundant. So nothing to worry, it just proves this feature actually works.

Thank you. This is the answer was hoping for. Just curious, how did you learn about this? I don't remember seeing it in any of the release notes, or maybe I missed it. Anyway, thanks for your help.
